Data URI: Inline a Small File and Cut a Round Trip

September 12, 2026

Every image or font in a web page is a request that can fail or slow the page. For tiny assets, a data URI removes that request entirely. Hand-encoding base64 is something nobody should be doing manually.

Encode text or a dropped file as a base64 data URI. Use it for small images in emails, where server paths are unreliable, and for one-off assets under a few kilobytes that you inline into CSS or HTML.

Try it now: open the free tool, runs 100{b8b7921c843ac9e5edcbca134af59decad3ed340e0e3b2e6c286158f277affea} in your browser.

Bottom line: inline small assets to save a request when it is worth it.

Your turn: use the tool free here, no signup, nothing leaves your device.
